CHANGEABLE EXHIBITOR.

Specification of Letters'Patent.

Patented Aug. 15, 1916.y

Application filed July 16, 1914. Serial No. 851,370.

To all whom t may concern Be it known that we, EUGENE O. MAN and CHARLES H. QUIST, citizens of the United States, residing at Denver, in the county of Denver and State of Colorado, have invented certain new and useful 1mprovements in Changeable Exhibitors, of which the following is a specification.

This invention relates to changeable exhibitors, and has for its object to provide an exhibitor attachable to railway rolling stock especially designed for holding placards conforming with the interstate commerce regulations.

Another object of the invention is to provide a changeable exhibitor embodying a holder having a spring actuated section constituting a front wall and having a plurality of placards secured against removal therein and adapted to be moved to a position for display in front of said spring actuated section.

'Vith these and other objects in view, the invention consists in the novel construction, arrangelnent and formation of parts as will be hereinafter specifically described, claimed and illustrated in the accompanying drawings, in which- Figure 1 represents a front elevation of the changeable exhibitor, Fig. 2 represents an end elevation thereof, showing one of the covers of the compartment in open position, Fig. 3 represents a vertical sectional view on the line 3-3 of Fig. 1, Fig. 4 represents a transverse sectional view on the line %4 of Fig. 1, Fig. 5 represents a transverse sectional view on the line 5-5 of Fig. 1, showing the cover of the compartment in open position and the placards in side elevation, Fig. 6 represents a vertical sectional view on the line 6-6 of Fig. 1, Fig. 7 represents an enlarged detail View of the changeable exhibitors, partly broken away, showing one of the placards in extended position, and Fig. 8 represents an enlarged detail sectional view taken at right angles to Fig. 7 illustrating the manner of positioning the placard in front of the spring actuated section.

Referring to the drawing in detail,

4wherein similar reference numerals desiga plurality of spaced partitions 13. Strips preferably formed of metal and designated by the numerals 14 are secured over and proyect laterally from the partitions 13 which latter divide the holder into four compartments 15, 16, 17 and 1S. The righthand side wallll above the two lower compartments 17 and 18 is cut away and the open sides of the two upper compartments 15 and 16 are adapted to be closed by hinged doors 19 secured by suitable hinges to the rear wall l0 and secured in closed position by suitable fasteners 20. Strips 21 are secured to the front faces of the compartments and project inwardly of the side walls thereof.

Movable sections or followers 22 are positioned within the compartments 15 and 16 and normally retained in engagement with the rear faces of the strips 14 and 21 by springs 23. Rear-ward movement of the followers 22 is limited by the guides 24 secured to the rear wall 10 of the holder and terminated in spaced relation to the strips 14 and 21. 'A plurality of placards 25 are vmovably inclosed within the compartments 15 and 16. Strips 26 are secured by rivets or the like 27 to the rear faces and longitudinal edges of the vplacards 25. The ends of the horizontally disposed strips 14 adjacent the open sides of the compartments 15 and 16 are directed rearwardly at 29 and secured to the rear wall 10 of the holder and are adapted to be engaged by the laterally projecting ears 28 carried by the strips 26 to prevent the placards 25 from being completely withdrawn from their compartments. The upper strips 14 are provided with lateral extensions 30 adapted to be received between the longitudinal edges of the placards 25 and the strips 26.

The placards 25 in the upper compart ments 15 are suitably marked to indicate thev character of various cargoes as required by the interstate commerce regulations, while the placards in the lower compartments 16 are provided with any desired markings. Any one of the placards in either of the compartments 15 or 16 is moved to operative position by withdrawing the placard to the position illustrated in Fig. 7 and subsequently moving it inwardly in front of the follower 22 in such manner that the lateral extensions 30 of the strips 14 are slidably received between the longitudinal edges of the placards 25 and the strips 26 as clearly shown in Figs. 6 and 8. The spring actuated followers Q2 engage the strips 2G and thus reliably hold the placards in position.

The followers 32 are movably disposed within the lower compartments 17 and 1S and arc normally retained in forwardly eX- t'ended position by springs 331K Horizontally disposed members 33 having bifurcated ends receiving Ahe side strips 21 are mounted for vertical adjustment infront of the followers 32. inspection and destination cards are adapted to be removably clamped in position for inspection between the lower followers and adjustable members That we claim is:-

l. A placard holder comprising a receptacle, a spring actuated follower in said receptacle, and a plurality of placards positioned behind said follower, movable to positions infront of the latter and secured against removal from said receptacle.

2. A placard holder comprising a receptacle, strips secured to the front face of said receptacle, a spring actuated follower in said receptacle normally engaged with the rear faces of said strips, and a plurality of placards secured against removal from said receptacle and movable to positions in front 0f or behind said follower.

tacle, strips secured to the front of said receptacle and extending rearwardly thereof, a spring actuated follower in said receptacle normally engaged against the rear faces of said strips, a plurality of placards in said receptacle movable to positions in front of or behind said follower, and means for securing said placards against removal from said receptacle including ears carried by said placards adapted to engage the rearwardly extending portions of said strips.

et. A placard holder comprising a receptacle, strips secured to the front of said receptacle, a spring actuated follower in said receptacle normally engaged against the rear faces of said strips, a plurality of placards in said receptacle movable to positions in front of or behind said follower, laterally projecting ears on said placards to prevent the removal of the latter from said receptacle, and strips secured to the rear faces of said placards adapted to cooperate with the first mentioned strips to guide said placards in position in front of said folf' lowers.

In testimony whereof we atlix our signatures in presence of two witnesses.
